We see it every time Bitcoin goes to a new lower level.
Bitcoin "believers" will hurry to say "buy the dip" and "just wait it will come back"
Reality is that every dip is a new lower level - and after that comes another dip...and another.
In the beginning of 2017 very few people had Bitcoin - and therefore the price could quickly move up as a large number of people with zero financial understanding started buying Bitcoin.
Now a large number of people with zero understanding has Bitcoin and price moves down - there are no more new fools to get into Bitcoin to ever pump it again.
"Buy the dip" is something only fools believe - and as can be seen in here there are unfortunately many fools in here who do not understand that their money is already lost
"buy the dip" still attracts someone or several groups of people to buy cheaper than it should be when indeed the price is cheap, they will wait even cheaper and continuously like that, so indirectly making a dump price, when the price is a dump, it will be very difficult to recover then they tried FOMO in various ways
